Summary

Weather Forecast

10-25cm forecasted for the Icefields Parkway Thursday night and into Friday, which will be accompanied by moderate south winds. The weekend will bring scattered flurries, light winds with mainly cloudy skies.

Snowpack Summary

On lee slopes, wind slab sits on top of a 5-10cm thick crust between roughly 2100m and 2600m. These slabs may be touchy in cross-loaded areas within the elevation band where the crust exists. Facets are present on top of the crust and will be the layer to watch with the incoming storm snow.
